FineTek JFR3 FMCW Radar Level Transmitter

E-Paper 01.13.2020

JFR3 FMCW radar level transmitter is a non-contact measuring device, suitable for liquid measurement in most tanks. It is easy to stall, convenient to maintain, and can be used in high temperature, high pressure and corrosive applications. With its high precision and stability, it is widely used in liquid level detection and process control in the industrial field.

FMCW radar (JFR) adopts a high frequency (GHz level) scanning method; electromagnetic waves are transmitted from the antenna to the target to be measured, then reflected to the receiver over time. During this period, a frequency difference will appear, which can be further calculated to obtain the distance from the transmitting end to the measured object. This distance is then converted to measure the amount of liquid in the tank.
